We have recently taken over a commercial property who were supplied electricity through BES. After lots of hard work we've finally managed to change the electric supplier to EDF. Much better contract and much less money. BES want to charge us for the period between taking over the tenancy and today. The rates they have stipulated are a £1.50 standing charge per day, and a rate of 22p per KWA usage. Are the above rates fixed? Is there any way we can object and get a lower tariff? Seems harsh that we never entered a contract with BES, yet they are able to charge us these ridiculous rates, because the previous tenants dealt with them. Any help much appreciated.
